Answer:
Atoms.
They come together so they can form molecules (because of their electrons)
It becomes a covalent bond
Explanation:
Answer:
The answer is C: .588 M
Explanation:
[CaCl2] = mols CaCl2/Liters of solution
molar mass of CaCl2 = 110.98 g/ 1 mole (from periodic table)
800 mL/1000 mL = .8 Liters of solution
1)
52.3g CaCl2/ 110.98g = .47 mole
2)
.47 mole/.8 L = .589 M
So the answer is C
<span>Biotic and Abiotic Factors Form Ecosystems. In a healthy forest community, interacting populations might include birds eating insects, squirrels
eating nuts from trees, mushrooms growing from decaying leaves or bark,
and raccoons fishing in a stream. In addition to how individuals in a
population interact with each other, let me know if it helps :)</span>
Answer:
The yearly release of into the atmosphere is .
Explanation:
Annual production of CaO =
Moles of CaO :
According to reaction, 1 mole of CaO is produced along with 1 mole of carbon-dioxide.
Then along with of CaO moles of carbon-dioxide moles produced will be:
of carbon-dioxide
Mass of moles of carbon-dioxide:
The yearly release of into the atmosphere is .
Large polymers are formed when small molecules are combined together to form a polymers, these small molecules that are combined together are called to be the monomers. In the given choices above, the correct answer that describe how the large polymers are formed is the last choice which says that they combined many different and smaller molecules.
